TYPE-WRITING MACHINE.

To all whom it may concern Be it known that I, BURNHAM C. STICK- 'NEY, a citizen of the United States,'residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type Writing Machines,'of which the following is a specification.

This invention relates to 'typewriting machines adapted to write different languages 'm which the lines of one language are written or printed inthc reverse direction from those of the other language. In certain languages, as for example Hebrew or Arabic,

the lines of writing or printing'i'un from the right toward the left, instead from left to right as in English and other modern languages. I

In accordance with the present invention, a paper carriage may be driven in either direction, and two sets of types representing languages in which the lines of writing run 3 in opposite directions, may cooperate with letter-feeding mechanism to control the v r travel ofthe carriage, and permit a letter- V feedmovementof the carriage 1n the direction corresponding to the language being written.

.In carrying out the invention, the paper i carriage is shifted from one set of types to language, and the types of the other set comprise the characters of a language written from right to left. Means for. driving the carriage in either direction, depending upon which language is belng written, may

comprise spring drums or motors adapted to be selectively connected by draw bands to the carriage. lVhen the carriage is moved into a position to cooperate with one set of types it is automatically connected with a.

motor for driving the carriage in theletter-' feeding direction required in writing the ltng'uage represented by said types. When the carriage .is shifted to the zone of the "otherset of types it is automatically discon- .inocted from the;first motor and connected to the other motor ho be driven in" the re verse direction.

Specification of Letters Patent.

Patented Nov. *7, 1916.

Application filed January 16, 1914. Serial No. 812,433.

The carriage may be connected to the motors through draw bands .and hooks on the ends of the draw bands held in position to be picked up by lugs on the carriage.

I each motorbemg thus connected to the carriagc as the latter is moved into the printing zone corresponding to said motor. Separate letter-feed mechanisms may control the letter-feed \movcments of the carriage in opposite directions, and letter-feed rack bars may be mounted on the carriage and may have their teeth faced in opposite directions,

one rack cooperating with an escapement' mechanism permitting a feed of the carriage from right to left, and the other rack co-.

operating with an escapement mechanism for feeding from left to right.

Other objects and advantages will hereinafter appear. 7

In the accompanying drawings, Figure l is a perspective plancview of a machine constructed in accordance with the principles .being near the center of the right hand ma chine Fig. 1. Fig. 6 is a rear elevation, the carriage being shifted to the opposite end Fig. 1.. Fig. 7 is a detail sectional plan showing the spring motors and draw bands. Fig. 8 is a detail View of a hook to be con-- nected to a draw band. Fig. 9 is a View similar to'Fig. 6 but with the carriage in an intermediate position.

In practising the invention in the form illustrated, the frameworks 1 and 2 of two Underwood front strike typewriting machines may be rigidly mounted on a common base 3 and may also be rigidly con-'- nected by front and rear carriage rails A: and 5, each of which rails extend from the left hand end of the frame 1,,to the right handend of the frame 2. A paper carriage 6, which may be an Underwood typewriter carriage of the usual construction, is mount ed for travel on the rails 4 ind 5, rolls 7 on the carriage running in a groove in the rail 4, and bearing lugs 8 or; the carriage,

,of the tracks from the position shown in sli-dable on the rear rail 5. A. rotary platen 76o trolling the letter-feedmovement of the carheii'ig held depressed manually while the type keys are struck. and the shift k 52 provided with the usual means-for lOCliluy, it in depressed position while inuse.

'lhe leftdiand keyboard 15.) may be provided with shift keys t) and 57 which operate in the same manner as the keys 51 and 52. to actuate the shift rail 59 for liftingthe carriage when the latteris in the lefthand printing zone.

\Vhen the carriage is in the righthand printing: zone. its position at the beginning of a writing: line, is determined by a margin stop 59 adjustable along a rod 60 and carrying a pointer (31 moving over a scale (can the front rail 4 to indicate the position of the stop. ,A. similar stop 63 carrying a pointer 64 moving over a seale 65, serves a like purpose when the. carria 1c is in the left.-

.hand zone. That is, in each instance the stops 59 and (i3 determ ne the position of the carriage at the beginning of a linefof writing. It will be noted that the two scales ()2 and 65 read in opposite directions. to agree. with the opposite letter-feed movements of the carriage.

Variations may hercsorted to within the scope of the invention, and portions oit the improvements may be used without others.

Having thus described my invention, I claunf bank for actuating the second-named mecha nisxn. 2.
